I disagree with this. Iowa, Wisconsin, Mizzou, Nebraska, even (sigh) Minnesota have been able to develop strong line play using kids from the midwest.
There is no reason ISU can't follow this same mold. There is certainly an uphill recruiting battle when Wisconsin and Iowa are so well known for putting linemen in the NFL, but if ISU wants to establish their identity (and I think they should) as a team focused on being physical at the point of attack and filling in the gaps from there, they can with the kids around here.
I should have worded my comment better I think. The big beef eaters that ISU is getting...not overall...the ones that ISU gets. Unfortunately we can't compete in getting the big boys from the midwest against teams like Wisconsin, Nebraska and even unfortunately Eastern Iowa University. That is why I think we need to start hitting the JCs hard for big, mean, mauling O linemen. Start a tradition of 1000 yard rushers, put some O linemen in the pros, and then we may be able to start stealing some of those guys from the more prominent schools.
